如何以编程方式添加Webview
[英]How to add webview programmatically
问题描述
当您想以编程方式添加Webview时遇到了问题，我尝试过这样的操作，但是当按钮已经可以显示时Webview无法显示，我需要针对这种情况的解决方案
// sizeView
LinearLayout.LayoutParams sizeView = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.MATCH_PARENT
);
// viewButton
Button home = new Button(this);
home.setText("HOME");
Button profile = new Button(this);
profile.setText("PROFILE");
Button academic = new Button(this);
academic.setText("ACADEMIC");
Button register = new Button(this);
register.setText("REGISTER");
Button about = new Button(this);
about.setText("ABOUT");
// viewWEB
WebView webView = new WebView(this);
// sideLeft
LinearLayout sideLeft = new LinearLayout(this);
sideLeft.setOrientation(LinearLayout.VERTICAL);
sideLeft.setLayoutParams(sizeView);
sideLeft.setBackgroundColor(Color.GRAY);
sideLeft.addView(home);
sideLeft.addView(profile);
sideLeft.addView(academic);
sideLeft.addView(register);
sideLeft.addView(about);
// wrapper
LinearLayout layWrap = new LinearLayout(this);
layWrap.setBackgroundColor(Color.BLUE);
layWrap.setOrientation(LinearLayout.HORIZONTAL);
layWrap.addView(sideLeft);
layWrap.addView(webView);
setContentView(layWrap);

您的WebView正确呈现。 只需启用所需的功能，例如使其启用javascript并设置chrome客户端和loadUrl即可使其正常工作...
同时，您还可以通过添加以下行来对其进行测试：
webView.loadData("<html><body>TEST</body></html>", "text/html", "utf-8");

LinearLayout layWrap = new LinearLayout(this);
layWrap.setBackgroundColor(Color.BLUE);
layWrap.setOrientation(LinearLayout.HORIZONTAL);
layWrap.addView(sideLeft);
setContentView(layWrap);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT);
FrameLayout.LayoutParams linearlayoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.MATCH_PARENT);
layWrap.setLayoutParams(linearlayoutParams);
layWrap.addView(webView);
webView.setLayoutParams(layoutParams);
webView.setBackgroundColor(Color.RED);
// to enable javascripts
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setBuiltInZoomControls(true);
// zoom if you want
webView.getSettings().setSupportZoom(true);
// to support url redirections
webView.setWebViewClient(new WebViewClient());
// extra settings
webView.getSettings().setLoadWithOverviewMode(false);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollContainer(true);
// setting for lollipop and above
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_COMPATIBILITY_MODE);
webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}
webView.loadUrl("http://www.facebook.com");
完成加载webview
